To all whom it may concern:

Be it known that I, FRANK PHILLIPS Do- RIZZI, a subject of the King of Great Britain, and resident of 66 Elm Grove road, Barnes,

. in the county of Surrey, England, pencil manufacturer, have invented certain new and useful Improvements in and Relating to Pencil-Making Machinery, of which the following is a specification.

This invention relates to machinery for the manufacture of pencils and has for its main object to provide mechanical means for inserting the leads or other material preferably with the combination therewith of gluing means.

Leading means constructed in accordance with this inventioncomprise a series of hoppers arranged over a suitable bed along which the grooved boards to beleaded are slid and means connected to each of said hoppers for feeding a single lead or strip of other material to each groove in the'board at the required moment. Said feeding means comprise for each hopper an outlet to said hopper of such width as to allow of the passage ofa single lead the'rethrough, two or more pairs of arms mounted on a rocking shaft and disposed so as to receive therein.

one lead from said outlet and adapted to be then partially rotated so as to deliver said lead and to hold back the supply of-leads in the hopper, me'ansfor causing such partial rotation of the arms and delivery oftthe lead at the required moment, and means may be provided for agitating the leads in proximity to the outlet to prevent then from becoming jammed.

Reference is to be had to ing drawings forming a part of this specifica- 1'. tion in which similar characters of reference indicate corresponding parts in all the figures. Figure 1 is a side elevation of one form of machine for gluing and leading pencils in accordance with this invention. Fig. 2 is a lan thereof. Fig. 3 is a cross section on line lI-II of Fig. 2 drawn to an enlarged scale. a is a hopper adapted to be charged with boards I) already grooved for the reception of the leads, and with agroove on the reverse side thereof for guiding the board through the machine as will be hereinafter described and as is well known in connection with rounding machines for pencils. The boards I) are charged into the hopper a with the lead grooves uppermost. Below the hopper a the accompany-- are arranged a number of feeding rollers 0 adapted to feed forward the lowest board I) along a bed at on which is a longitudinal proj ection adapted to engage the groove in the reverse sideof the boards I) and to guide said boards during their passage through the machine. On leaving the hopper a the board passes over a roller e between a guide e and spring e and its front end is engaged between a pair of rollers f, g, of which the lower 9 is driven by the same gearing as the feeding rollers and the upper f, called the timing roller, is frictionally rotated by the passage of the board 1) 'therebelow. From the timing roller f the boards I) pass along the bed at below a roller 1 l to the gluing means and thence below the leading means. The boards are thus fed through the machine in a constant stream and are successively glued and leaded. The timing roller f is designed according to the requirements of the machine, for instance where it is desired to supply leads to every alternate board, the circumference of said timing roller is equal to the length of two of such boards. The timing roller f is connected to the leading means by a lever h pivoted at i to the bed d of the machine, one end of said lever being )rovided with a friction roller j and adapted to-be acted upon by a cam on the, timing roller f. The other end of the lever it is connected to and adapted to reciprocate a rack m with which mesh pinions a adapted to partially rotate rocking shafts 0 each carrying two pairs of arms which select and deliver a single lead from the outlet 7 of each hopper r, to a chute 13.

s is a spring adapted to effect the return motion of the rack m, and tie a set screw for adjusting such return motion.

a are rods carrying cams o for agitating the leads before they are selected by the arms 10, said rods being adapted to be rotated bya worm w and worm wheels such as at driven by a pulley y and belt 2 from a pulley 2 connected to the main driving means.

3 and 4 are'fast and loose pulleys mounted on a shaft 5 having a bevel pinion 6 gearing with another bevel pinion 7 on a shaft 8 on which are mounted the roller 9 and the pulley 2.

9 are bevel pinions meshing with like pinions on shafts 10 on which are mounted the feeding rollers c. 4

The gluing means comprise a box 12 of metal (such as lead) or other suitable substance, open at the top and bottom and arranged above the bed so as to allow of the passage of the boards 5 between said box and the bed d and provided with means for sup plying the said box with glue or other ad- 'lhe'lower 1 edges of two sides of said box are formed L hesive from a source of supply.

nation with the gluing apparatus described or with any other means for gluing.

lf desired the machine can be arranged to glue all the boards, but to lead alternate boards only as described, so that every pair of boards fed out of the machine may be placed together by hand, or if required by a further movement of the same machine. In another form the machine may be designed to lead every board and may be connected with a second machine in which boards are glued but not leaded and a board may be taken from each machine and placed together by hand or otherwise.

By the use of a machine constructed in accordance with this invention much hand labor and time are saved.
